CW Sidetone ideas

 

Good day all
I enjoy using various vintage "separates" on CW, with a bug.
The common issue is what to do for sidetone when using a straight key or bug. Typically,? not music the Rx, and have a fast hand on the RF gain control works well.
But, Collins and Drake have a sidetone.?
Has anyone added a sidetone to HT44/ SX117 or HT32B/SX101 SX115 combos?

The simplest way is to connect an external tone oscillator to pin 8 of J3 Through a diode.

I use the several Curtis keyers that are boatanchor proof, and can be set for paddles or manual keying.

Great suggestions. I have a external sidetone oscillator, and will give the “Pin #8” option a try. Once, I used a TO Keyer that I’d modified to accept a straight key input as an sidetone. Unfortunately, I don’t have that any longer.

I used one of these in a SR 150


It was powerful enough to just parallel across the speaker lines and drive the speaker directly.?

I've just started to work on a CW sidetone technique for the HT-44.? Great idea of Walt's to use a diode and pin 8 of the octal plug to accomplish the keying.? I built a little LM555 based sidetone oscillator based on the design at AA8V's website.? I found that I could connect the output to the 500 Ohm terminal on the rear of the SX-117 and that enables you to hear the sidetone in the headphones or the speaker.? Haven't worked out any volume differences yet.

Floyd,

When you get all the kinks out of?the side-tone mod, post a schematic of your project.

A note: some old CW practice oscillators were set up to be keyed by
a sample of RF from the transmitter to provide a side tone. For instance
the Bud Radio oscillators. Should not be difficult to do this with a
solid state oscillator although I don't have a circuit. A simple pick up
loop will trigger the oscillator. I have not tried my Bud oscillator but
it can probably feed the receiver speaker of phones with a simple
parallel connection.
I used to mostly listen to my own signal via the station receiver
but that doesn't work if you are using two separate frequencies.

When using a straight key, I do ok by listening to the sound of the key,
but I can't do that with a bug. Back in the '50s I had a 100TH with 866
rectifiers. The humming of the transformer laminations when I pressed
the key was all I needed.

Walt - The sidetone generator is complete and working well.? The generator circuitry is housed in an external minibox and there are zero modifications to the SX-117 or HT-44.? All connections to the gear are external.? No special parts required other than the high voltage PNP transistor.? I'm not an engineer and I suspect there are more elegant ways to accomplish this, but it does work well for me.? Here is the schematic and a photo of the unit.

It's been a long while, but I recall a simple battery powered stand-alone side tone generator that worked quite well by simply responding to RF . No attachment at all to the transmitter or receiver. When I have time, I'll look back in my archives for schematics and other data. I was also using the HT-44 / SX-117 combo.? (Currently stored away now, but in pristine condition).?
 

I use noise-cancelling headphones much of the time on CW and a stand-alone generator could not be heard.??
 

I know I'm late to the party, but the old Electronics Illustrated "Scrounger" 10 Watt 6V6 tube transmitter project (Link here: ) had a 1 transistor "keying Monitor" that one could make to monitor the CW tone. Just relaying in case in one would be interested.
